[TowerTalk] Manually crank down a motorized tower

[Joe K2UF]

 Bob,

I have a 72 foot tri-ex tower .  Have never user the motor control for it.
I have cranked it up and down manually many times.  You are correct it takes
a lot of cranking.  Once I counted the turns.  It took about 1000 revs to
lower each section ( also 1000/sect. back up  UGHHH).

Good luck,

73  Joe K2UF

I have a US Tower HDX589MDPL with the motorized drum.  I was wondering what
I would do in the event that something failed in the control box and I
needed to crank it down.
The gearbox has a worm gear and I believe I could temporarily take off the
chain and turn the gear box sprocket by hand.  I would have to turn it until
the cows come home but I think I could crank it down.  Am I correct about
this ?  Have any of you had to crank down your motorized tower by hand ?
